Example from pedometer package not working?

Question

I have installed the blank flutter app with ONLY pedometer package :

dependencies:
  pedometer: ^3.0.0

And paste this source, compiled without errors, but in-app :

Step Count not available

I installed other libraries, they work, what's the point?

Flutter doctor:

Device data:

One UI version

Android Version

Google Play system update

Chat GPT things:

The Flutter pedometer package should be compatible with the Samsung Galaxy A10 running One UI 3.1 and Android 11, 
as well as the Google Play system update from April 2021.

Answer 1

you should add , permissions to use the package,

For android:

For Android 10 and above add the following permission to the Android manifest:

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />

For ios:

Add the following entries to your Info.plist file in the Runner xcode project:

<key>NSMotionUsageDescription</key>
<string>This application tracks your steps</string>
<key>UIBackgroundModes</key>
<array>
    <string>processing</string>
</array>
